Be it known'that l, Gnoncn D. Pocos, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful mprovement in Valveless Liquid-Elevating Devices, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to devices of the character that are used for raising a liquid from a lower to a higher level.

The main object of my invention is to pro- A vide a device for elevating liquids that is not equipped with valves, stuffing boites or coperating rubbing parts that are-subjected to wear and which require frequent adjustment Another object is to provide' a liquid elevating device of the character just referred to, which is so constructed' that the amount of liquid raised and discharged by same can be .controlled or regulateda Another' object is to provide a liquid raisu ing device that is particularly adapted for use in the circulatin system of a water cooled internal com ustion engine and which is so constructed that the water is caused to circulate through the water space or jacket of the piston without the necessity of subjecting such space to any pressure relative to the surrounding atmosphere, thereby overcoming the necessity of using valves or stung boxes, asis necessary with the water cooled pistons now in use.

And still another object is to provide a simple and reliable means for lubricating the piston pin bearings oli an internal com; bustion engine equipped with pistons orf? the trunk type. Other objects and desirable fea.-

`tures of my invention will be hereinafter pointed out" A .To this end l have devised a lliqu1d ele vating device thatv consists'merely of a recip-l rocating member, preferably a conduit, provided with liquid holding portions or devices arranged atdift'erent levels and constructed in' such a manner that the reciprocating movement of said member will cause the liquid to be thrown upwardly from a lower device to a Y higher device until it inally reaches the point where it' is to be discharged. Said liquid holding portions or devices can be constructed in various ways without departing from the spirit of my invention, but they preferably consist of projections, flanges, cups or shelves arranged on the interior of said conduit and open at their' upper sidesor upper ends so that the liquid which is displaced and forced upwardly into the lower end of said conduit when it dips into or reciprocates in a body of liquid will be caught by the liquid holdn ing devices at the lower end of the conduit and thereafter thrown upwardly into the liquid holding devices arranged higher up on the conduit by the subsequent reciprocating movements of the conduit, said liquid eventually reaching the u per end of the conduit and escaping there rom. The liquid holding portions extend throughout the entire length of the conduit, or, at least, up to the level where the liquid is to be raised and discharged, so that the liquid from the source of supply will be raised progressively or by a `step by step action to a point in proximity to the highest liquid holding portion on the conduit. While l prefer to use of liquid, various other means-could be used for supplying the liquidto said member without departing from the spirit of my invention.,

My improved liquid elevating device can be used or'so many purposes that l will .not attempt to enumerate all of the various uses `of said device. lt is particularly adapted for use, however, in internal combustion engines for supplying cooling water to the water jacket of the piston and for supplying lubricating oil to the piston pin bearing of a trunk type piston, on account of the fact that it .does not comprise stuiiing boxes, accurately fitted valves or coperating rnb- `loing parts that are subject to Wear or liable tn qet. out of adjustment. y Therefore, l have vtor supplying cooling water to the piston and for supplying lubricating oil to the piston pin bearing.

Fig. 2 is an enlarged vertical sectional view, illustrating the construction and arrangement of the liquid holding devices arranged inside oit' the reciprocating conduit up through which the liquid is ralsed; and

Fig. 3 is a similar view, illustrating al slight modification of my invention.

Referring to the drawings, A designates the lpiston of the engine which is of the trunk type and provided with a water jacket' or space 1 in the upper portion of same through which water is circulated, so as to cool the top of the piston, said piston also having internal lugs or bosses 2 (only one of which is shown) that receive the usual pin B upon which the upper end o f the connecting rod 3 is pivotally mounted. Cooling water is supplied to the water jacket or space l in the upper portion of the piston by means of a reciprocating member C, preferably a conduit that is mounted on the piston A in such a 4manner that its upper end terminates in or communicates with the water space 1 1n the piston and its lower end terminates in or communicates with av stationary water reservoir D to which water is supplied by means of a pipe 4 equipped with a controlling valve 5 that is governed by means of Ya float 6 arranged in the body of liquida in the reservoir D. The water is conducted-.away from the water jacketor space in the piston through a discharge pipe 7 carried by the piston and arranged in such a manner that the lower end of same terminates 1n or commumcates with a stationary discharge reservoir E fron v which a discharge pipe 8 leads.

The reciprocating member C is provided with water holding portions or devices `C which are so arranged that they form a seriesof flanges, projections or cups o n the interior of said member C, and when the engine is in operation said water holding portions coperate with each other to raise A the water progressively or by a step by step action from the reservoir into the -water -jacket 1 in the piston. In the form of my invention herein shown the water holding portions on the reciprocating conduit C are formed by la number of devlces arranged one above the other inside of said conduit Laemmli y and each provided with an annular outer wall 9 that fits snugly inside of the'conduit and a hollow cone-shaped center portion `10 whose lower edge is connected to said outer wall 9 and whose upper end is provided with a discharge hole 11, as shown clearly in Fig.-2. The annular space 12 between said outer wall 9 and said cone-shaped center portion l0 forms a pocket that receives and holds the liquid that is thrown upwardly through the center opening 1'1 in the device when the conduit C is in operation. The devices C are securely connected to the conduit C, and if desired, rings 9il of lead or other suitable material can be arranged between said devices and the inner surface of the conduit C, so' as to form water-tight joints between said parts.

When the conduit C moves downwardly into the water in` the supply reservoir D, one or more of the liquid holding devices C at the lower endof said conduit will be lled with water. As the conduit continues in operation, ,the impulses or agitation that is imparted to the water in the liquid holding portions C at the lower end of the conduit will throw said water upwardly into one or more ofthe liquid holding portions C arranged higher up in the conduit until said water linally reaches the liquid holding portion C at the upper end of the conduit from which it is ldischarged into the water /space l in the piston. As previously stated, it is immaterial how the liquid holding portions on the reciprocating member are formed, but I have found that liquid holding devices C of the kind herein shown are veryefiicient, due to the fact that the coneshaped center portions 10 of same guide the liquid into the center openings 1l up through which the liquid travels. Said portions also tend to guide the liquid away -fromv said openings after it has passed through said openings. lf desired, baiiies '13 can be arranged between the devices C', as shown in Fig. 3, so as to eliminate the possibility of the water passing downwardly through the alined openings 11 inv said devices, but these baiiies 13 are not essential to the successful operation of my device.

In order to prevent the water in the receiving reservoir D from splashing out of same and escaping into the crank case vwhen the reciprocating conduit C is in operation, I have provided said reservoir D with an upwardly-projecting tubular portion D that surrounds` the conduit C, said tubular portion being provided adjacent its upper end withbatlies. formed 'by downwardlyinclined annular flanges 14 arranged one above the other and spaced in close prox.- imity to the outer surface of the conduit C, as shown in Fig. 1.' The discharge reservoir E is also provided with an upwardly-pro-- jecting tubular portion E that surrounds the discharge pipe l', said tubular portion being equipped with baties les for a similar purpose., The receiving reservoir l) is \preferably in open communication with 'the atmosphere at all times through a 'vent l5, but the discharge reservoir E is preferably `provided with means that causes a partial vacuum to be created in the discharge reserlo l voir E when the piston A moves upwardly, thereby tending to remove er strip any `waterthat clings to the outer surface ot the discharge pipe 7 on the upward strolre of the piston. ln the form ol my invention hereinshown thisk is accomplishedby providing the discharge reservoir E with a vent 15a that is equipped with .a dep valve 16. 0n the downward lstroke of the piston the valve 16 opens and prevents pressure from 20 building up in the discharge reservoir, but on the upward stroke of the piston said valve closes, and thus causes a partial vacuum to be created in the discharge reservoir andin the tubular extension E* on same that surrounds the discharge pipe 7. A water cooling system of the construction above described is simple to manufacture and maintain in operative condition, because 1t does not comprlse stuiiing boxes, aceu' rately fitted valves or any cooperating sliding parts that are liable to wear and, which require frequent adjustmentn ln addition 'to the desirable features above mentioned, such a system enables the quantity oit water that is supplied tothe water jacket of the piston to be controlled or regulated by simply adjusting the device 6a that governs the position of the doat 6 in the supply reser voir that holds the water inlet valve 5 closedu 40 When the body of water :e in which the lower end of the conduit C reciprocates is relatively deep, more water will be supplied. to the waterjaclret l of the piston at each cycle of operations/of the piston than when. `said.

body ofwater is comparatively shallow'.

The means employed for supplyinglubri eating oil to the piston. pin bearing 2 ernu bodies the same desirable features and char acteristics as the means previously described tu for supplyingwater to the water jacket l of the piston and consists ofl a conduit F carried by the piston, preferably hy one of the lugs or bosses 2, a stationary oil container G into which the lower end portion of said .conduit F projects, and oil holding portions or devices F arranged on the interior of said conduit F throughout the entire lenogth of same and constructed in substan tially the same 'manner as the liquid holding devices Cf on the conduit C, Any means 'can be used forsupplying oil to the oil reservoir G, but l prefer to use a drip feed device 17,\as shown in Fig. l, that discharges oil into a funnel 18 on the upper end of asup- @5 ply pipe 19Y which leads to the oil reservoir G. lllhen the piston is in operation oil will he carried upwardly progressively through v the conduit F from oil reservoir G to the piston pin bearing 2, By regulating the drip feed device l? the operator in charge of the engine can accurately control the quantity of oil tiet supplied to the episton pin herringn l Having thus described my invention, what l' claim, and desire to secure hy Letters Plat l ent, is:
